Answer:
The level was 402.7ft. at the end of two weeks.
Step-by-step explanation:
First, we need to find the amount of decrease for the first week.
520 x 0.12 = 62.4
Now, we subtract the change for the first week.
520 - 62.4 = 457.6
Next, we find the change for the second week.
457.6 x 0.12 = 54.912
Then, we subtract the change for the second week.
457.6 - 54.912 = 402.688
And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
You just have to multiply the numerators and the denominators.
The answer is 14 over 56. Then, you need to simplify the question.
So, since 56 is divisible by 14, divide the numerator and the denominator by 14.
Then you get your answer, which is one-fourth.
Hope that helped!
Answer:
C
Step-by-step explanation:
Because i'm smart and did the math.
Answer:
6. x + x + 14 = 90
2x + 14 = 90
2x = 76
x = 38
angle b = 38 + 14 = 52°
7. angles on a straight line add up to 180°
x + x - 32 = 180
2x = 212
x = 106°
angle d = 106 - 32 = 74°
8. vertically opposite angles are equal
7x - 80 = 3x
-80 = -4x
20 = x
angle 1 = 7(20) - 80 = 60°
angle 2 = 3(20) = 60°
